1 anim. (c1. 21e- 75l -Ihe invention relates to dispensing devices andmore particularly to devices for dispensing liquids such as perfumes,shaving lotions, Yand the llike receptacles.

The object Yof t-he invention is toprovide a dispensing device wherebyV7the-expulsion of the liquid from thecontainer may be controlled atwill and which is constructed in a simple manner so as to reduce thepossibility-of dislocation 'of the parts to a minimum.

"The :invention contemplates further `the provision of a novel andsimple dispensing device designed in addition toits other functions toserve as -a closure 'for the receptacle in which the liquid iscontained. l

A further object ofthe invention is to provide a simple and nov-eldispensing device which may be readily sealedat will to preventunintentional spilling of the contents of the receptacle and to enablethe latter and its contents to be 'carried about, for instance, in atraveling bag without danger of spilling lsaid contents.

Other objects of the invention will appear from the descriptionhereinafter, and the features of novelty will be 'pointed' out intheclaim.

In the accompanying drawing, which illustrates an example of theinvention Withoutk dening its limits,

Fig. 1 is an elevation of a receptacle with the novel dispensing devicein place thereon;

Fig. 2 is an enlarged vertical section of the novel dispensing device;and

Fig. 3 is a plan View thereof.

In the illustrated example, the novel dispensing device is shown in theform of a closure for receptacles such as a bottle 5 in which the liquidto be dispensed is contained.

The dispensing device itself comprises a sleeve 6 suitably fixed uponthe neck 'I of the bottle or other container 5, said sleeve including aninwardly-directed annular flange 8 which is internally screw-threaded asillustrated in Fig. 2.

The dispensing device further includes a hollow member 9 threaded intothe flange 8 and including an annular outwardly-directed ange I0 whichprojects over the flange 8 of the sleeve 6. If desired, a gasket I I ofsuitable resilient or other packing material may be located between theflanges I0 and 8 for preventing leakage at this point.

At its upper end, the member 9 is internally screw-threaded for thereception of an externallythreaded bushing I2 having anoutwardly-directed flange I3 adapted to lie in surface engagement withthe flange l0. The bushing I 2 is in- 2 ternally screw-threaded at'least throughout a part of its length as indicated at 1'4.

A vtubular 'spoutv I5 extends axially through the bushing I2 in opposite4directions and is in screwthreaded engagement with 'the threads M of.said bushing' I2, and at its inner end, is provided With an .annularflange 'ljslidablyLIittingthe interior of the member 9 as shown in'.Fig. 2;

The tubular spout I5 includes 'an'axal passage I'I which 'terminates atits lower end :in a valveseat I8 located Iin Vspaced .axialregistryjwith alcooperating valve-'seat "I9 lformed at the 'inner vendof a passage 20 with which the member 9 is vprovided wand whichestablishes communication between the interior of the latter 'and theinterior of therecep'tac'le. Aball-valveiLZI is" located in thevinterior 'of thefmember 9 and .is movable between the valve-seats. "I sand'1,9"for 4cooperation therewith, in the vmanner to'be describedhereinafter, to Acontrol the 'dispensing of. the; liquid con-A tained inthe bottle or other .container 5..

IIn 'order that the, ball v.alve.`2| may lalways automatically roll into'position upon the seat- 'I9` to seal the passage2ll, 'when thisisdesired, the bottom of the member 9 preferably'is inclined toward saidpassage', 'for instance, as illustrated 'in Fig. 2,. The inclinationmaybe 4at Vany suitable angle to effect the intended result, an angle of59 has been found to give satisfactory results.

As illustrated in Fig. 2, the parts of the novel dispensing device areadjusted to permit the dispensing of the contents of the bottle or othercontainer 5. As long as the latter remains in an upright position, theball-valve 2l will remain in place on the valve-seat I9 and thereby sealthe opening 20 to prevent evaporation of the contents of said bottle 5or other unintentional disposal thereof.

In this adjustment of the parts, the valve seat I8 is located at adistance from the valve-seat I9 so that if the bottle 5 or othercontainer is tilted or inverted, the ball-valve 2| will leave thevalveseat I9 and position itself in the interior space of the hollowmember 9 between the tWo valveseats or said ball-valve may even seatitself upon the passage 20 into the interior of the member 9 and thenceout to the passage I'I of the dispensing spout I5 in such quantity asmay be desired. This is dependent upon the length of time during whichthe bottle 5 or other container is manipulated as described and may alsobe regulated by adjusting the spout I5 in the bushing I2 to regulate thedistance between the two valve-seats I8 and I9. After a given dispensingoperation has been completed, the bottle 5 or other container isreturned to the upright position illustrated in Fig. 1 in which theball-valve 2| automatically reseats itself upon the seat I9 and therebyseals the passage 20 to prevent evaporation and other 'loss of thecontents of said bottle or other receptacle 5.

If it is desired to carry the receptacle 5 with its contents, as, forinstance, while traveling from place to place, the novel dispensingdevice may be adjusted to lock the ball-valve 2| on the seat I9 tothereby prevent any leakage of the contents from the bottle 5 or otherreceptacle through the passage 20. This is accomplished by adjusting thedispensing spout I5 downwardly in the bushing I2 until the valve-seat I8iirmly engages the ball-valve 2| and clamps it against movement of anykind relatively to the Valve-seat I9.

The novel dispensing device may be readily combined with bottles orother receptacles either so as to be removable therefrom at will andthus capable of being reutilized or the device may be permanentlysecured to the bottle or other receptacle and discarded therewith whenthe liquid contents have been fully disposed of.

The novel dispensing device is extremely simple in construction and,accordingly, is not likely to easily get out of order and, at the sametime, is of maximum eilciency for its intended purposes.

'I'he novel dispensing device may be made of metal or any other suitablematerials and is particularly adapted to be made of plastics such asLucite and the like.

When the novel dispensing device is removably combined with the bottleor other receptacle 5 as illustrated in Fig. 2, the hollow member 9 andits associated elements may readily be removed from the sleeve 6 topermit refilling of the bottle or other receptacle 5 at will.

While the novel device is designed primarily 4 to control the dispensingof liquids such as perfumes, shaving lotions, and the like, it obviouslymay be utilized for controlling the ejection of other types of liquids,and in some forms, may be used for controlling the dispensation of othertypes of materials.

Although the present invention has been described in conjunction with apreferred embodiment, it is to be understood that modifications andvariations may be resorted to Without departing from the spirit andscope of the invention, as those skilled in the art will readilyunderstand. Such Variations and modifications are considered to bewithin the purview and scope of the claim.

I claim:

A dispensing device of the kind described comprising a sleeve adaptedfor connection with a receptacle and having an inwardly-directed annularflange internally screw-threaded, a hollow memberthreaded into saidsleeve and having a passage provided with a valve-seat at one end, aninternally-threaded bushing threaded into said hollow member, a tubulardispensing spout threaded into said bushing and provided with avalve-seat at its inner end in spaced relation to said rst valve-seat,and a ball valve in said hollow member movable between said valve-seatsto control ejection of the liquid contents of said receptacle, andautomatically returning to one of said seats at the conclusion of anejecting operation, to seal the receptacle against losses of itscontents, said dispensing spout being adjustable Y to clamp the ballvalve between and in sealing engagement with both of said valve-seats toseal the contents in said receptacle.
